If I understand your concern,it is that there is too much negative influence for kids today.Well.you can act to limit some of it.When they are very young you,you can influence what they watch on t.v. making sure that it is educational and thought provoking and not just entertainment for the masses.But the best thing is to be always open and honest with them.
